Pros:

FUN!
Reward for staying alive.
Cool, yet different.
No bugs or glitch spots
Exploration fun with each time period achieved

Cons:

none

Conclusion:

Love this, every bit as good as originals.

Pros:

interesting
fun
lots of cool modifiers
great reward for beating Gold time
great replay value, as you'll never use all the extras in one round

Cons:

not really anything to complain about, the add-ons work well esp. considering how truly ambitious they are.  I don't love the drug references, but they are mostly tongue-in-cheek.  

Conclusion:

Very, Very good survival map.  Purists like myself may not want to try the "mini-people" type of thing, but believe me, this is a very fun board.
